will serve in holding seat cushions from displacement, and the principal object of the present in- Vention is to provide a unitary construction in which means are provided for anchoring the edging to the frame of a seat in such manner as to prevent rolling up of the edging and to maintain the edging permanently in proper position. The invention also comprises a method of producing an edging of this character.

Usual upholstery edging comprises a substantially cylindrical body having a core around which a layer of felt is wound and provided with lateral contacting extensions with a covering surrounding the body and overlying and underlying the extensions thereof, with means securing the overlying and underlying covering to the iin. The fin is then secured to the spring covering at a distance from the spring frame of the spring construction so that a portion of the body of the edging projects beyond the spring frame. In such old constructions when in use the edging is likely to roll upwardly thereby distorting the finishing covering which overlies it and thus mars the appearance of the article of furniture to which it is applied.

In order to overcome this defect it has been heretofore customary to secure the covering of the edging to the spring covering or to the wire of the frame by manual stitching by a curved needle which is diilicult and consumes considerable time. Furthermore such stitching is likely to give way and thereby to permit the edging to roll up in the manner described.

The object of the present invention is to provide a unitary edging which can be economically produced with a minimum amount of labor and which will provide an anchoring flap preferably extending throughout the length of the edging and which when applied to a seat can be readily secured by tacks or otherwise to the frame of the seat in such manner as to maintain the edging permanently in proper position and prevent any distortion of the edging throughout the life of the article of furniture upon which it is employed. Preferred embodiments of the invention and method of making the same are illustrated in the accompanying drawing, in which,

Fig. 1 is a conventional representation of a seat provided with a spring for supporting the cushion or the springless seat having suitable means replacing the spring;

-Fig. 2 is a vertical sectional View illustrating a step in the method of forming a spring covering in which a short section of covering is secured to a longer web of covering adapted to be wrappedv upon a suitable body in the manner hereinafter described;

Fig. 3 is a vertical sectional view of one form of fibrous body for the edging showing a core having wrapped around it a layer of felted material with extensions thereof providing the body with a. lin adapted to be covered and secured to the spring covering of a furniture seat;

Fig. 4 is a vertical sectional View illustrating the steps in the method for producing one form of edging embodying the invention;

Fig. 5 is a detail view mainly in vertical section showing a portion of the frame of a seat for an article of furniture, the spring frames, one of the springs, the covering therefor, and the upholstery edging embodying the present invention mounted thereon; and,

Fig. 6 is a vertical sectional view showing a modiiied form of edging embodying the invention.

The method of producing the edging embodying the present invention comprises first forming a body Yof fibrous material having a suitable fin. A preferred method which is illustrated in Fig. 3 comprises providing a core l, which may be substantially cylindrical compacted fibrous material or which may be in the form of a rope or otherwise, which is surrounded by a layer of felt 2 to enclose the core I and to provide contacting extensions 3 and 4 forming a 1in extending laterally from the core with the extension 3 preferably substantially tangential thereto. The next step of the method as illustrated in Fig. 2 consists in placing a web or short base section 5 of suitable fabric, such as burlap, upon a longer Web of fabric 6 and securing an overturned edge of the section 5 to the fabric by aline of stitching 'l in such position and in such proportions that the section 5 will extend from the edge of the iin approximately to the vertical plane of the core oi the body with the longer web 6 comprising a section 8 adapted to form an anchoring iiap and a section 9 of such length as` to extend around the body and overlie the n, as illustrated in Fig. 4. The next step in producing the edging embodying the present invention consists in seaming to gether at or adjacent to the base of the fin, the fin and the overlying and underlying layers of' fabric by a line of stitching I0 or other suitable means which will maintain the cylindrical form of the body and fin throughout the length thereof. Preferably one or more lines of stitching I I connect the overlying and underlying layers and the fin Vof the body therebetween at a suitable distance remote from the line of stitching mand the ends .of the covering sectionsV 5 and l!v andthe .iin'therebetween 'are futher secured together by overseaming I2 tov provide a finished edge.

t will be noted that in this construction the section 8 is only attached to the body by a line of stitching I so that the flalpf is adapted to extend downwardly for attachment to the body of the seat.

Fig. 5 illustrates the manner in which the edging embodying the present invention is secured to a spring covering. In the construction thus illustrated the furniture seat comprises a frame frame I4 upon which suitable. springs I5'are mountedv in the usual-mannergthe upper ends of the 'Y spring being similarly mounted upon an --upper wire'framef I6. 11A suitable spring covering "I 'I of burlap,for other suitable material, is mount- -ed"upon-andfextends uacross the-upper spring frame I5, and thence downwardly and secured wat its lowerend to-theseatframe I3by tacks or infanyothersuitable'frnanner. "In the constructionas-shown in Fig.5 the edging is secured-to fthe "springI lcovering `by manual `oversearning I 8. *Ther-anchoring iiapftl is then bent: downwardly at substantially right angles-.to r'the underlying section-"5V of theedging cover -andiislsecured by side of the se'atframe I3.v
